The umbrellas are gone and the sunscreen has made a glorious return to the Bay Area, where an unseasonably warm stretch broke temperature records in the Peninsula and East Bay and came close in San Jose.

But after soaking up the heat for a couple of days, the Bay Area should cool down a bit Friday, with temperatures back to normal this weekend.

Fittingly enough, just in time for baseball’s opening day, Thursday was the hottest last day of March on record for part of the Bay Area. It was 80 degrees at San Francisco International Airport — cruising past the previous high of 76 set in 2000 — and a record 83 degrees in Oakland. In San Francisco, the temperature hit 82 degrees, tying the previous high mark.

The mercury needed to tick up a couple of degrees to break records in the valley, however. It was 81 degrees in San Jose — four shy of the record set in 1966 — 85 in Santa Cruz and 84 in Gilroy.

It’s quite a shift from last week, when a cloudy day with temperatures in the low 60s was considered a nice respite from the storms.

“Looks like at least spring is here,” said National Weather Service meteorologist Austin Cross.

Temperatures will drop a few degrees Friday compared to Thursday, Cross said.

“Then this weekend we expect it to cool down quite a bit, into the low to mid-60s,” Cross said. He said it could be a little cloudy this weekend but that the storms should be over. “Then it should get pretty nice again next week.”

For those hitting the water this weekend, forecasters warn of treacherous waves, with the shore a safer — and less windy — bet.

Violent police encounters in California last year led to the deaths of 157 people and six officers, the state attorney general’s office said Thursday in a report that provides the first statewide tally on police use-of-force incidents.
